It installs a Nokia X virtual device, so even if you’re not developing for the Nokia X now, you can get a feel for what Android connecting to Microsoft services feels like.

I just tried it out and, oddly, it doesn’t use Bing for search, but rather uses Google. The contacts & calendar apps and “Add Account” in the Settings app, however, do ask for Exchange credentials. (I just did some more research and it looks like this virtual device is just for testing your services–it doesn’t look like the UI on the actual Nokia X phone, and doesn’t include all the bundled apps such as Bing and Outlook.)
